61 / 138 page  MPC5644A Microcontroller Data Sheet, Rev. 7 Freescale Semiconductor 61 BOOTCFG[0:1] SIU - Configuration Two BOOTCFG signals are implemented in MPC5644A MCUs. The BAM program uses the BOOTCFG0 bit to determine where to read the reset configuration word, and whether to initiate a FlexCAN or eSCI boot. The BOOTCFG1 pin is sampled during the assertion of the RSTOUT signal, and the value is used to update the RSR and the BAM boot mode See the MPC5644A Microcontroller Reference Manual for more information. The following values are for BOOTCFG[0:1}: 00:Boot from internal flash memory 01:FlexCAN/eSCI boot 10:Boot from external memory using EBI 11:Reserved Note: For the 176-pin QFP and 208-ball BGA packages BOOTCFG[0] is always 0 since the EBI interface is not available. WKPCFG SIU - Configuration The WKPCFG pin is applied at the assertion of the internal reset signal (assertion of RSTOUT), and is sampled 4 clock cycles before the negation of the RSTOUT pin. The value is used to configure whether the eTPU and eMIOS pins are connected to internal weak pull up or weak pull down devices after reset. The value latched on the WKPCFG pin at reset is stored in the Reset Status Register (RSR), and is updated for all reset sources except the Debug Port Reset and Software External Reset. 0: Weak pulldown applied to eTPU and eMIOS pins at reset 1: Weak pullup applied to eTPU and eMIOS pins at reset. ETRIG[2:3] SIU - eQADC Triggers External signal eTRIGx triggers eQADC CFIFOx GPIO[206] ETRIG0 (Input) SIU - eQADC Triggers External signal eTRIGx triggers eQADC CFIFOx GPIO[207] ETRIG1 (Input) SIU - eQADC Triggers External signal eTRIGx triggers eQADC CFIFOx IRQ[0:5] IRQ[7:15] SIU - External Interrupts The IRQ[0:15] pins connect to the SIU IRQ inputs. IMUX Select Register 1 is used to select the IRQ[0:15] pins as inputs to the IRQs. See the MPC5644A Microcontroller Reference Manual for more information.
